Could not load file or assembly 'itextsharp' or one of its dependencies

Trying to follow this tutorial for RazorPDF, and I don't know why am I getting the following error message: Very frustrated and tired.

Error Message:

Could not load file or assembly 'itextsharp' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

itextsharp:

RunTimeVersion: v1.1.4322 Version: 4.1.2.0

RazorPDF:

Run Time version: 4.0.30319

Inside the controller:

   public ActionResult Index()
    {
        var studentMarks = new List<MarksCard>()
        {
           new MarksCard()
            {
                RollNo = 101, Subject = "C#",
                FullMarks = 100, Obtained = 90},new MarksCard() {RollNo = 101, Subject = "asp.net", FullMarks = 100, Obtained = 80},new MarksCard() {RollNo =               101, Subject = "MVC", FullMarks = 100,
                Obtained = 100},new MarksCard() {RollNo = 101, Subject = "SQL Server", FullMarks = 100, Obtained = 75},
        };
       //// return new RazorPDF.PdfResult(studentMarks, "Index");
        return View(studentMarks);

    }

Inside View

@model IEnumerable<TimberBeamCalculator.Models.MarksCard>

@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

<p>
    @Html.ActionLink("Create New", "Create")
</p>
<table>
    <tr>
        <th>
            @Html.DisplayNameFor(model => model.RollNo)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Subject)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.FullMarks)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Obtained)
        </th>
        <th></th>
    </tr>

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.RollNo)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Subject)

        <td>
            @Html.DisplayFor(modelItem => item.FullMarks)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Obtained)
        </td>
        <td>
            @Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) |
            @Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ }) |
            @Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ })
        </td>
    </tr>
}

Check to be sure that you actually have iTextSharp going into the correct place. My guess is you are missing something.

I'd strongly suggest you start by following the initial project samples and trying to get them to work first.

• Intro video (2 mins video showing you what to do to make it work.)
• Sample projects of Github
